The controller 20 is further configured to control the first limiting device 12 to limit the first limiting bearing 10, so that the first limiting bearing 10 can move along the transmission slide bar 22, and control the second limiting device 16 to limit the second limiting bearing 14, so that the second limiting bearing 14 can drive the connecting block 13 to rotate.

The controller 20 is further configured to receive pressure values collected by the pressure sensors 19, and control the first limiting device 12 and the second limiting device 16 according to the pressure values.

The pressure sensor 19 disposed on the first clamping plate 4 is a first pressure sensor, and the pressure sensor 19 disposed on the second clamping plate 9 is a second pressure sensor.

In some of these embodiments, in the event that the controller 20 detects that the pressure value collected by the first pressure sensor reaches the pressure threshold value, it indicates that the first clamping plate 4 has clamped the load on the upper part of the fork; in the case where the controller 20 detects that the pressure value collected by the second pressure sensor reaches the pressure threshold value, it indicates that the second clamping plate 9 has clamped the load on the upper part of the fork. Wherein the pressure threshold is used to indicate that in this pressure situation the first 4 or second clamp plate 9 has clamped the load on the upper part of the fork.

In some of these embodiments, in the case where the first clamping plate 4 clamps the goods but the second clamping plate 9 does not clamp the goods, i.e. the controller 20 detects that the pressure value collected by the first pressure sensor reaches the pressure threshold value, but the pressure value collected by the second pressure sensor does not reach the pressure threshold value, at this time, the controller 20 controls the first limiting device 12 to open, so as to release the locking of the first limit bearing 10, and enable the sliding block 23 in the first limit bearing 10 and the outer ring of the limit bearing main body 24 in the first limit bearing 10 to relatively slide, at this time, the controller 20 can control the driving assembly 3 to continue working, so as to drive the driven screw rod 33 and the driven worm 34 to continue rotating, thereby drive second grip block 9 and continue to rotate to continue to carry out the centre gripping to the goods, thereby avoid appearing the problem that the good centre gripping of first grip block 4 centre gripping goods but the good centre gripping of second grip block 9 can not the good centre gripping goods.

In some embodiments, when the goods are not clamped by the first clamping plate 4 but the goods are clamped by the second clamping plate 9, that is, the controller 20 detects that the pressure value acquired by the first pressure sensor does not reach the pressure threshold, and the pressure value acquired by the second pressure sensor reaches the pressure threshold, at this time, the controller 20 controls to start the second limiting device 16 to release the second limiting bearing 14, even if the driving assembly 3 continues to drive the driven worm 34 to rotate, the driven worm 34 does not drive the connecting block 13 to rotate, and the controller 20 controls the driving assembly 3 to continue to work, so that the goods are clamped by the first clamping plate 4.

Each first limiting hole 11 is located on the outer ring and the inner ring of the first limiting bearing 10.

Under the condition that the first limiting column 26 penetrates through the second limiting hole 7 and enters the first limiting hole 11, the first limiting column 26 can limit the outer ring and the inner ring of the first limiting bearing 10, so that the outer ring and the inner ring of the first limiting bearing 10 cannot rotate relatively, and the sliding block 23 cannot rotate relatively with the outer ring of the first limiting bearing 10.

When the first stopper post 26 is separated from the first stopper hole 11, the outer ring and the inner ring of the first stopper bearing 10 are unlocked, so that when the slider 23 rotates along with the transmission slide bar 22, the slider 23 can rotate relative to the outer ring of the first stopper bearing 10 via the inner ring of the first stopper bearing 10, and at this time, the slider 23 is not displaced by the rotation of the transmission slide bar 22.

One end of the first limiting torsion spring 27 is disposed on the sidewall of the first limiting groove 6, and the other end thereof is fixedly connected to the lower end of the first limiting plate 25, so as to apply a torsion force to the first limiting plate 25, so that the first limiting plate 25 passes through the second limiting hole 7 and enters the first limiting hole 11 to limit the first limiting bearing 10.

The first electromagnet 28 is disposed on the other side wall of the first limiting groove 6, arranged corresponding to the upper end of the first limiting plate 25, and electrically connected to the controller 20, and configured to control the first limiting plate 25 under the control of the controller 20, so that the first limiting post 26 can leave the first limiting hole 11.

For example, when the controller 20 energizes the first electromagnet 28, the first electromagnet 28 attracts the upper end of the first stopper plate 25 away from the first stopper hole 11 to release the stopper of the first stopper bearing 10; under the condition that the controller 20 de-energizes the first electromagnet 28, the first limit plate 25 passes through the second limit hole 7 and enters the first limit hole 11 due to the torsion of the first limit torsion spring 27, so as to limit the first limit bearing 10.

under the condition that the second limiting column 30 penetrates through the fourth limiting hole 18 and enters the third limiting hole 15, the second limiting column 30 can limit the inner ring and the outer ring of the second limiting bearing 14, and the inner ring and the outer ring of the second limiting bearing 14 are prevented from rotating relatively.

Under the condition that the second limit column 30 leaves from the third limit hole 15, the second limit column 30 releases the limit of the inner ring and the outer ring of the second limit bearing 14, so that the outer ring and the inner ring of the second limit bearing 14 can rotate relatively, at this time, if the driven worm 34 rotates, the driven worm 34 can drive the inner ring of the second limit bearing 14 to rotate in the outer ring of the second limit bearing 14, and the connecting block 13 and the second clamping plate 9 cannot be driven to rotate.

One end of the second limiting torsion spring 31 is disposed in the second limiting groove 17, and the other end of the second limiting torsion spring 31 is fixedly connected with the rear end of the second limiting plate 29, so as to provide torsion for the second limiting plate 29, and enable the second limiting plate 29 to pass through the fourth limiting hole 18 and enter the third limiting hole 15 to limit the inner ring and the outer ring of the second limiting bearing 14.

The second electromagnet 32 is disposed on the other side wall of the second limiting groove 17, arranged corresponding to the front end of the second limiting plate 29, and electrically connected to the controller 20, and configured to control the second limiting plate 29 under the control of the controller 20, so that the second limiting column 30 can leave the third limiting hole 15, and the limitation of the second limiting bearing 14 is released.

For example, when the controller 20 energizes the second electromagnet 32, the second electromagnet 32 generates a magnetic force to move the second stopper post 30 away from the third stopper hole 15 to release the stopper of the second stopper bearing 14; under the condition that the controller 20 cuts off the power of the second electromagnet 32, the second limiting plate 29 is moved toward the fourth limiting hole 18 under the torsion action of the second limiting torsion spring 31, so that the second limiting post 30 passes through the fourth limiting hole 18 and enters the third limiting hole 15 to limit the second limiting bearing 14.

Wherein the second limit plate 29 is made of a magnetic material, such as iron.
